The Panama Canal has officially opened to neo-panamax vessels, allowing larger ships direct access to U.S. East Coast ports, which could lead to significant changes in shipping routes and rates. Experts predict that 10-14% of container traffic may shift from West Coast to East Coast ports, potentially driving down freight rates due to increased competition. This shift could have financial implications for carriers, as they may need to lower rates to attract cargo amid a new influx of larger vessels.
